Description
The vulnerability allows an adjacent attacker to execute arbitrary code on the host system.
The weakness exists due to a stack-based buffer overflow in the processing of L2CAP configuration. An adjacent attacker can submit a specially crafted Bluetooth protocol, trigger memory corruption in the Bluetooth stack and execute arbitrary code in kernel space.
Successful exploitation of the vulnerability may result in host system compromise.
